A mixture of 6-bromo-3-methylimidazo[1,5-a]pyridine (100 mg, 0.47 mmol), 1-(3,4-dihydroisoquinolin-2(1H)-yl)-3-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)propan-2-ol (211 mg, 0.52 mmol), K2CO3 (195 mg, 1.41 mmol) and Pd(dppf)Cl2 (10 mg) in a solution of dioxane (4 mL) and H2O (1 mL) was stirred at 120° C. for 30 minutes under microwave heating. The catalyst was filtered, the filtrate concentrated and the residue purified by Prep-HPLC to give the desired title product as a colorless oil and formate salt (15 mg, Yield 7%). 1H NMR (400 MHz, MeOD) δ 8.13 (s, 1H), 7.57 (d, J=4.8 Hz, 1H), 7.42 (dd, J=8.0 Hz, 1H), 7.31-7.11 (m, 7H), 7.09-7.00 (m, 2H), 4.53-4.49 (m, 1H), 4.42 (s, 2H), 4.15 (d, J=4.2 Hz, 2H), 3.57 (t, J=6.4 Hz, 2H), 3.43-3.36 (m, 2H), 3.18-3.16 (m, 2H), 2.68 (s, 3H). LCMS (m/z): 414.2 (M+1).
